RAILWAY.

SPECIFICATION forming part of Letters Patent No. 426,052, dated April 22, 1890.

Application filed May 25, 1889.

To all whom, it may concern:

Be it known that I, MOSES XVHITE OLIVER, of Lawrence, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Railways, of which the following is a specification.

The object of this invention is, first, to furnish a support for the common rail of a railroad or railway in such a manner that the weight borne by a passing wheel shall be distributed on twoor more cross-ties, (or on two or more parts of any kind of' substructure,) and so that the said weight can never come wholly on one crossrtie or on any one point of the substructure, and, second, to make such support elastic, whereby the railroad superstructure is made uniformly elastic within its own construction, and the weight of the train is diifuse'd over as great an extent of the substructure as possible; To-accomplish these objects I place a sub-rail beneath the common rail and'upon the cross-ties or substructure, and upon the sub-rail, between it an d the common rail, 1 place at intervals blocks or plates which directly support the ordinary rail, allas below set forth, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a railwayrail to which my invention is applied, a portion being represented as broken out. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a cross vertical section on line as, Fig. 1. Fig; at is a cross vertical section on line g}, Fig. 1. Fig. 5 is a cross vertical section on line .2, Fig. 1.

A is a common railroad-rail.

B is a sub-rail of any convenient shape resting on the cross-ties G or the substructure.

I) D are blocks or plates upon the sub-rail and between it and the common rail. These blocks D are placed. between the cross-ties, preferably midway, and directly support the rail A, so that over the cross-ties there are open spaces between the sub-rail and common rail. By this meansI accomplish a better distribution and diffusion of the'weight borne by each passing Wheel upon the crossties or substructure, and avoid the concentration of the Whole of said w eight upon each and every cross-tie or upon a single point of the substructure, is the case with the com- Serial No. 312,126. (No model.)

mon track, occasioning the depression of the cross-ties irregularly into theballast andotherwise disturbing and distorting the track, so as to cause wear and tear to track and rolling-stock and requiring frequent tamping up of the cross-ties and other repairin Again, by means of my improvement I ob tain a constantly uniform and beneficial clasticity of the track within its own construction without necessarily depressing the crossties unduly into the ballast. This cannot be obtained with the common track, which has no beneficial elasticity except whatis allowed by the yielding or depression of the cross ties or other substructure.

In carrying out my invention I propose to secure the common rail A, blocks D, sub rail B, and substructure together in any suitable and practicable manner.

In the drawings, at a joint of the common rails, (see Figs. 1, 2, and 3,) fish-plates E E, connections E E, and clamps E E are made integral, as shown, and hold the com mon rail, sub-rail, and supporting-block, the clamps E extending under the edges of the sub-rail, bolts and nuts to bpreventing the block from slipping out, and bolts and nuts 0 (Z securing the fish-plates E to the common rail.

Between the cross-ties, where there is no joint of either rail, (see Figs. 1, 2, and 6%,) the block D may be provided at one edge with the integral double clamp D and at the opposite edge with the integral screw D over which a double clamp F is held by means of the nut 6. At a joint of the sub-rails (see Figs. 1, 2, and 5) double clamps H H hold the rails, while bolts and nuts g it connect said clamps, and as said bolts pass through on opposite sides of the block D said block is held in position. The sub-rail is secured to the cross-ties in any ordinary manner. If desired, a base-plate I may stretch from one cross tie to the next across and beneath the joint of the sub-rail, as shown in Figs. 2 and 5. In practice the joints of the rails A are placed at about the middle'of the rails B, and the joints of the rails B at about the middle of the rails A.

By means of my invention there is such distribution. and diffusion of weight and uni IOC form elasticity of the track that the wear and tear 0t the road-bed, bridges, track, and rolling-stock is reduced, and in consequence the noise decreased, conveyance made safer and more comfortable, and the cost of maintenance diminished.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is-

1. In combination with the ordinary rail A, sub-rail B, and intermediate blocks D, the

clamps H and bolts and nuts g h, arranged substantially as and for the purpose described.

2. In combination With the ordinary rail A, sub-rail B, and intermediate blocks D, the r 5 integral clamps and fish-plates E E E and 1 bolts and nuts a b, arranged substantially as and for the purpose set forth.
